I would consider " an area up North" correct though, or is there some nuance that I'm missing?
Added. It's marked as informal in the dictionary, but no doubt:
Headword north. Phrases: up north. Informal , To or in the north of a country: he’s taken a teaching job up north
Why is just 'nord' considered as 'the north'. I wrote down 'An area in north', but shouldn't it be like 'norden' or something then?
Norden is the official name for the Nordic countries, Norway, Sweden, Finland, Iceland, Denmark, Åland and Faroe Islands. Capital N in Norden. Norge, Sverige, Finland, Island, Danmark, Åland og Færøyene.
Magnetic directions are nouns but sort of uncountable. It has but one form, nord. I nord = In the North. Mot nord = To the North. Fra nord = From the North.
Thank you both, I'm not a native English person so I didn't know it was incorrect.
